Bolton Wanderers midfielder Fabrice Muamba is showing small signs of improvement after he suffered a heart attack in Saturday's FA Cup match against Tottenham Hotspur.

Muamba, 23, remains critically ill in intensive care at the London Chest Hospital's heart attack centre, but his heart is now beating without medication and he is moving his arms and legs, a club statement said.

Medical staff attempted to resuscitate the former England Under-21 international but could not get his heart to start beating on its own for almost two hours after he collapsed after 41 minutes of the match at White Hart Lane.

"Fabrice Muamba remains in intensive care at The London Chest Hospital, where today he is showing small signs of improvement," the statement read.

"His heart is now beating without the help of medication and he is also moving his arms and his legs.

"However, his long-term prognosis will remain unclear for some time. He is still critically ill and will continue to be closely monitored and treated by staff in The London Chest Hospital's intensive care unit."

Bolton chairman Phil Gartside and manager Owen Coyle visited the hospital on Monday morning.

In a statement on the club's website, Gartside said: "The staff at the London Chest Hospital have been nothing short of exceptional and I would like to thank them all at this ongoing critical time.

"The support we had from Tottenham and our own fans was fantastic - the staff, the fans, the players and the officials at the game - it was unbelievable."
